Abstract

Tetragonal Ba_0.8Sr_0.2TiO₃ thin films with large columnar grains 100-200 nm in diameter have been prepared on Pt/Ti/SiO₂/Si substrates using a 0.05 M solution precursor by sol-gel processing. The ferroelectric phase transition in the prepared Ba_0.8Sr_0.2TiO₃ thin films is broadened, and suppressed to 40 °C with a maximum dielectric constant of ∈_r (100 kHz)=680. The observed low dissipation factor tan δ=2.6% and high pyroelectric coefficient p=4.586×10^-4C/m² K at 33 °C render the prepared Ba_0.8Sr_0.2TiO₃ thin films promising for uncooled infrared detector and thermal imaging applications.
